+Eye/Primary rays: from camera into scene
+Shadow rays: rays from surface intersection point toward light source
+Reflection rays: from surface intersection point in mirror direction
+Transmission rays: from surface intersection point in refracted direction
+
+Algorithm:
+    - Send ray from camera through each pixel into scene
+    - Compute point of closest intersection with scene object
+    - Shade that point by computing shadow rays
+    - Spawn reflection and refraction/transmission rays and recurse
+
+When do we stop tracing?
+    - When the ray leaves the scene
+    - When the ray's contribution becomes too small

+Changes for 1.7.0:
+
+* New feature: death tests are supported on OpenBSD and in iOS
+  simulator now.
+* New feature: Google Test now implements a protocol to allow
+  a test runner to detect that a test program has exited
+  prematurely and report it as a failure (before it would be
+  falsely reported as a success if the exit code is 0).
+* New feature: Test::RecordProperty() can now be used outside of the
+  lifespan of a test method, in which case it will be attributed to
+  the current test case or the test program in the XML report.
+* New feature (potentially breaking): --gtest_list_tests now prints
+  the type parameters and value parameters for each test.
+* Improvement: char pointers and char arrays are now escaped properly
+  in failure messages.
+* Improvement: failure summary in XML reports now includes file and
+  line information.
+* Improvement: the <testsuites> XML element now has a timestamp attribute.
+* Improvement: When --gtest_filter is specified, XML report now doesn't
+  contain information about tests that are filtered out.
+* Fixed the bug where long --gtest_filter flag values are truncated in
+  death tests.
+* Potentially breaking change: RUN_ALL_TESTS() is now implemented as a
+  function instead of a macro in order to work better with Clang.
+* Compatibility fixes with C++ 11 and various platforms.
+* Bug/warning fixes.

-// Google Test defines the testing::Message class to allow construction of
-// test messages via the << operator.  The idea is that anything
-// streamable to std::ostream can be streamed to a testing::Message.
-// This allows a user to use his own types in Google Test assertions by
-// overloading the << operator.
-//
-// util/gtl/stl_logging-inl.h overloads << for STL containers.  These
-// overloads cannot be defined in the std namespace, as that will be
-// undefined behavior.  Therefore, they are defined in the global
-// namespace instead.
-//
-// C++'s symbol lookup rule (i.e. Koenig lookup) says that these
-// overloads are visible in either the std namespace or the global
-// namespace, but not other namespaces, including the testing
-// namespace which Google Test's Message class is in.
-//
-// To allow STL containers (and other types that has a << operator
-// defined in the global namespace) to be used in Google Test assertions,
-// testing::Message must access the custom << operator from the global
-// namespace.  Hence this helper function.
-//
-// Note: Jeffrey Yasskin suggested an alternative fix by "using
-// ::operator<<;" in the definition of Message's operator<<.  That fix
-// doesn't require a helper function, but unfortunately doesn't
-// compile with MSVC.
